There was no significant difference in pedicle angle between pig and human cervical vertebrae, while the height and width of the pig pedicle were slightly larger. Anatomical reference terms may be confusing because they are different for pigs that walk on four legs vs. upright, bipedal humans. 13.1: Respiratory System and Pig Dissection, { "13.1.01:_Fetal_Pig_Dissection_Lab" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "13.1.02:_Fetal_Pig_Dissection_Lab_(Instructor_Materials_Preparation)" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "13.1.03:_Reading-_Fetal_Pig_Dissection" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "13.1.04:_Cardiovascular_and_Respiratory_Systems_Lab" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "13.1.05:_Cardiovascular_and_Respiratory_Systems_Lab_(Instructor_Materials_Preparation)" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "13.01:_Respiratory_System_and_Pig_Dissection" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, https://bio.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fbio.libretexts.org%2FCourses%2FLumen_Learning%2FBiology_II_Laboratory_Manual_(Lumen)%2F13%253A_Module_10-_Cardiovascular%2F13.01%253A_Respiratory_System_and_Pig_Dissection%2F13.1.01%253A_Fetal_Pig_Dissection_Lab, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), Learn about the anatomy of the pig as an example of a vertebrate mammal, Identify structures on the pig and know their functions, Identify structures that are a part of the digestive system, respiratory system, circulatory system, reproductive system, and excretory system.

Intestines there is a significant difference in the structure of the fetal pig colon compared to the human colon. Pig cervical vertebrae had larger VBWs than human cervical vertebrae, whereas pig vertebral PI and SCW were nearly the same as those of humans in the middle and lower cervical vertebrae. The pig cervical spine is highly similar to the human cervical spine, except for two large transverse processes in the anterior regions ofC4C6. In the current study, we evaluated the geometries of cervical vertebrae in two animal models and normalized these parameters for comparison against human cervical vertebrae. For example, the length of many structures was found to vary significantly with feeding strategy. Vernier calipers (Gaozhi_0200, Shanghai, China; accuracy 0.03 mm) and a protractor, both meeting international standards, were respectively used to take linear and angular measurements.
